我看到了问题，但是在哪里，什么类型？任何建议如何找到它？

我尝试搜索 Dictionary< List<看看里面有什么，但运气不好。

InnerException是null

我试过调用 ProtoBuf.Meta.RuntimeTypeModel.Default.GetSchema(typeof(LinkBudgetScenario));同样没有帮助的信息。

是否有可能获得更有用的错误消息而不是内部无用的调试消息？

步骤:

1. 更新到 protobuf-net 2.3.0:https://www.nuget.org/packages/protobuf-net/2.3.0
2. 重新运行代码并阅读消息
